Too often I figure out how to do this or that on Linux systems and in my haste to complete whatever task I've been assigned this "How To" knowledge gets lost. So here, I will begin posting little odds and ends in hopes of not needing to re-research past efforts for Linux tips, tricks, hacks, and other good to know things. If you find yourself here and know of smaller, faster, better ways of doing any of this please let me know - only through cooperation can we all get better.

Executing the above command will display the output of some_program immediately in the console and write the same contents to output_file.txt.

I use this command mostly for diffs against svn, saves a step. Also, though I'm posting this as a Mac OS X terminal option, I first discovered this on Ubuntu 8.04 though I sure the history or this command is much older. I recall from the documentation to think of this in plumbing terms: Send your output down a pipe to a "T" essentially sending the same stream/flow to two different places.

From time to time it can be handy to remove subversion references from code that is sitting on the file system. The following command will remove all '.svn' directories from the current directory on down:

user@machine:~/dev/sample1$ rm -rf `find . -type d -name .svn`
